Color Flow Doppler Sonography of the Thyroid

Abstract

In the past, morphological evaluation of the thyroid gland relied primarily on the thyroid scan. In recent years high resolution sonography has became the first-line test in the assessment of thyroid morphology, due to its sensitivity, and easiness and because it avoids the use of radioactivity. Moreover, the ultrasonographic features of the gland may help to identify specific thyroid pathology as in the case of autoimmune thyroid disorders, characterized by diffuse hypoechogenicity (1,2).
